A knee prosthesis comprises tibial, meniscal and femoral components. Subluxation and/or rotation of the meniscal component with respect to the tibial component is controlled by means of a control peg 21 fitted between the tibial and meniscal components, and a bar 5 spanning the intercondylar notch of the femoral component provides posterior stabilization by bearing against a cam surface 8 of a protrusion extending upwardly from the center of the meniscal component.
